Definitions

  • a method for manufacturing a pneumatic tire according to the present invention for solving the above-described object is a method for manufacturing a pneumatic tire in which a green tire is deformed by a molding drum that is expandable and contractable in the tire radial direction in a tire molding process.
  • a non-adhesive sheet having a coefficient of friction of 0 to 0.2 with the molding drum is disposed on the innermost surface of the green tire, and the green tire is attached with the non-adhesive sheet attached thereto. It is characterized by molding.
  • the non-adhesion of the friction coefficient between the green tire and the inner surface of the green tire is low.
  • the green tire is deformed when the green tire is deformed by a molding drum that can expand and contract in the tire radial direction. It will slide smoothly on top. For this reason, the amount of deformation in the circumferential direction of the green tire becomes non-uniform, and the uniformity of the tire can be improved.
  • the uniformity of the tire can be further enhanced.
  • FIG. 1 schematically shows a molded drum for carrying out a method for manufacturing a pneumatic tire according to an embodiment of the present invention, where (a) is a side view in a reduced diameter state, and (b) is an enlarged view. It is a side view of a diameter state.
  • FIG. 2 is an enlarged view of a main part of a green tire in the method for producing a pneumatic tire of the present invention.
  • the green tire 11 includes a carcass layer 12 mounted on a pair of left and right bead portions, a rubber sheet 13 for an inner liner located inside the carcass layer 12, and the rubber sheet 13
  • the non-adhesive sheet 14 located on the inner side of the green tire is laminated, and the non-adhesive sheet 14 is disposed on the innermost surface of the green tire.
  • the non-adhesive sheet 14 may be present on the entire innermost surface of the green tire 11, but may be present at least in part.
  • the green tire formed into a predetermined shape through the tire forming process is vulcanized with a vulcanizer to become a product tire, but the description of the vulcanization process is omitted here.
  • the constituent material of the non-adhesive sheet 14 has a low coefficient of friction, and may be any material.
  • a thermoplastic elastomer including a thermoplastic resin or a blend of a thermoplastic resin and an elastomer is particularly preferable. It is preferred to use a composition.
  • the thermoplastic elastomer composition is obtained by dispersing a blend of elastomers in a thermoplastic resin matrix.
  • Examples of the elastomer include, for example, Gen rubber and hydrogenated products thereof [for example, NR, IR, Epoxidized natural rubber, SBR, BR (high cis BR and low cis BR), NBR, hydrogenated NBR, hydrogenated SBR], olefinic rubber [eg ethylene propylene rubber (EPDM, EPM), maleic acid modified ethylene propylene Rubber (M-EPM)], Butinole rubber (IIR), Isobutylene and aromatic bur or Geno monomer copolymer, Acrylic rubber (ACM), Ionomer 1, Halogen-containing rubber [eg Br-IIR, CI-IIR, Isobutylene Brominated paramethylstyrene copolymer (Br-IPMS), chloroprene rubber (CR), hydrin rubber (CHC, CHR), chlorosulfonated polyethylene (CSM), chlorinated polyethylene (CM), maleic acid modified chlorinated polyethylene ( M-CM)], silicone rubber (
  • thermoplastic elastomer composition other polymers and compounding agents such as a compatibilizer can be mixed as a third component in addition to the thermoplastic resin component and the elastomer component.
  • a compatibilizer can be mixed as a third component in addition to the thermoplastic resin component and the elastomer component.
  • the purpose of mixing other polymers is to improve the compatibility between the thermoplastic resin component and the elastomer component, to improve the film forming ability of the material, to improve heat resistance, and to reduce costs.
  • polyethylene, polypropylene, polystyrene, ABS, SBS, polycarbonate and the like can be used as the material used for this purpose.
  • Example 1 In a method for manufacturing a pneumatic tire in which a green tire is deformed by a molding drum that can be expanded and contracted in the tire radial direction in a tire molding process, a non-adhesive sheet is disposed on the innermost surface of the green tire, and this non-adhesive sheet After forming a green tire with the adhesive sheet attached, the green tire was vulcanized to obtain a pneumatic tire (Examples 1 and 2).
  • Example 1 a thermoplastic resin (polyester) having a coefficient of friction with the molding drum of 0.2 was used as the non-adhesive sheet, and the thickness thereof was set to 0.1 mm.

Abstract

Procédé de fabrication d'un pneumatique permettant d'améliorer son uniformité, comprenant une étape de moulage du pneu par un tambour de moulage extensible dans la direction radiale du pneu pour appliquer une déformation à un pneu vert. On dispose sur la surface la plus à l'intérieur du pneu vert une feuille non adhésive ayant avec le tambour de moulage un coefficient de frottement de 0 à 0,2 et on moule le pneu vert avec la feuille non adhésive plaquée sur lui.
